Micross’ qualified encapsulated space-grade MRAM utilizing Avalanche Technologies STT-MRAM, is a plastic encapsulated microcircuit screened and qualified to NASA’s electrical, electronic and electromechanical specifications. The 1Gb QED MRAM offers true random read/write access while being inherently highly resistant to magnetic flux & radiation, mitigating the need for radiation shielding while providing near infinite endurance and best-in-class non-volatile data retention. This MRAM device architecture is analogous to Flash technology with an SRAM compatible read/write interface with ECC and a Asynchronous Page Mode feature for enhanced performance.
